To all whom tt may concern:

Be it known that I, ROBERT L. MURDOOK, a resident of Bellevue, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Hinges; and I do hereby declare the following tobe a full, clear, and exact description thereof.

My invention relates to hinges and more particularly to that class ofhinges comprising two leaves with knuckles formed thereon through whicha pintle passes to hold the parts together.

The object of my invention is to provide a simple and eflicient meansfor preventing rotation of the pintle connectiugthe leavesso that in theworking of the hinge, the pintle will not rise or work out and therebyreduce the efficiency of the hinge and at the same time mar theappearance of same.

To these ends my invention comprises, generally stated, a hingecomprising two leaves with hinge knuckles, a plug entering the lowerknuckle, and pintle in removable non-rotary engagement with said plug.

In the accompanying drawing Figure 1 is a face view of my invention,with the hinge partly in section; Fig. 2 is a perspec tive view of thepintle; Fig. 3 is a perspective view of the plug, and Figs. 4, 5 and Gshow a modified form of my invention.

In the drawing the numerals 2 and 3 indicate the leaves of a suitablehinge. The leaf 2 is provided with the knuckles 1 and 5, and the leaf 3is provided with the knuckles G, 7 and 8. The lowermost knuckle 8contains the plug 9 which is such a snug titthat when driven within saidknuckle it will be held securely therein. The plug 9 may, however, besecured in place in any suitable manner. This plug 9 is provided withthe enlargement or bulb 10 which is to add to the finish of the hingeand correspond with the bulb 11 at the upper end of the pintle 12. Theinner end of the plug 9 is cut away as at 13 to form an interlocking ornon-rotary connection with the Vpintle 12, which is likewise cut-away atthe lower end as at 14, so that when the pintle 12 is inserted Wit-hinthe openings in the knuckles the lower end can be seated to engage thecut-away portion ofthe plug 9 and all rotary motion of the pintle isprevented while it is in engagement with said plug. In this manner Iprovide a simple and efficient means for preventing rotation of thepintle without in any way changing the construction of the hinge, andthe removal of the pintle is accomplished by simply lifting the same asin the ordinary manner.

In Figs. 4, 5 and G, I have illustrated a modified form of my inventionin which the plug 15 is cut away at its inner end to form the slot- 1Gwhich receives the reduced end portion 17 of the pintle 18. When thepintle is inserted it is turned until the portion 17 engages the slot 1Gof the plug, when further rotation of the pintle is prevented.

IVhat- I claim is:

1. A hinge comprising leaves and knuc kles, a plug engaging thelowermost knuckle, and a pintle in removable non-rotary engagement withsaid plug.

2. A hinge comprising leaves and knuckles, a plug engaging the lowermostknuckle, said plug having a cut-away portion, and a pintle engaging saidcut-away portion.

In testimony whereof, I the said ROBERT L. MURDOOK have hereunto set myhand.
